Factoring Trinomials using SlideDivideIf there is a trinomial that after checking
for GCF still has a number in front of the x2, factor using the slidedivide method.
3x2 2x 5
S Slide
1. Multiply the number in front of the x2 to the product and rewrite your trinomial.
3x2 2x 5
F Factor
2. Factor the trinomial using productsum.
3x2 2x 5
D Divide
3. Divide both numbers in factored form by the number that you slid (# in front of the x2).
3x2 2x 5
R Reduce
4. Reduce the fraction, if possible. If not, leave it alone until the next step.

S Slide
5. Take the denominator that cannot be reduced and slide it in front of the x in the same
parenthesis.
3x2 2x 5
Factor.
2x2 + 3x 9

Options for Factoring Questions1. Binomial > No GCF > Difference of Squares
2. Binomial > GCF > No Difference of Squares
3. Binomial > GCF > Difference of Squares
4. Trinomial > No GCF > x2 > Product Sum
5. Trinomial > No GCF > #x2 > Slide Divide
6. Trinomial > GCF > No x2 or #x2 (No Product Sum/Slide Divide)
7. Trinomial > GCF > x2 > Product Sum
8. Trinomial > GCF > #x2 > Slide Divide
9. Polynomial > GCF
